Without some means for holding the bucket stationary on theboom the mixing drum, :considerable material would be Wastedbecauseofthetendency of the: bucket to move outwardly "on the boom {isthe g aggregates ereipeured therein.

Formed' on the can! riageisan extensions with which e shuttle:

G is edapteditocooperetez The shuttle is r 7 formed with alongitudinalslot7 which is slidably engaged by the guide pins 8 securedto the extension in any suitable manner.

The shuttle is preferably formed with an extension 9 to which the endsof the bucket operating cable 10 are secured as at Fixed to the boom1,adjacent the lnward end is a stop member 12 which is adapted tocooperate with a latch member having a stop engaging arm 13, a shuttleengaging arm 14 and a third arm 15 which is adapted to cooperate with aspring 16 or other device for normally holding the latch member in stopengaging, position. Obviously any suitable 'means for producing thisresult might be "employed. The stop member is so positioned ing on eachside of the bucket.

along the boom asto cause the bucket to be held-in the proper positionwith respect to the discharge chuteifrom the mixing drum.

The shuttle 6 has formed on each endtransverse flanges 17 and 18. Anouthaul pull on able 10, assuming the'bucket to be in latched positionfor receiving the mixed batch from the mixing drum, causes the flange 18on the 'shuttleto, engageithe arm is ofthe latch member, therebyrotating the latchmember about the pivot 19 to the position shown by thedotted lines inFig. 3. Further movement of the cable causes'the shuttleto'shift on the guide pins until flange 18 engages the extension 5 ofthe carriage, whereupon motion is then transmitted to the carriage bythe cable. I 7 1 I J ournaledin the carriage in any suitable manner isthe actuating shaft 20 for operat-' ing the bucket opening andclosingmember or, door (not shown) in the usual manner, as

for example by means of the bell cranks 21 fixed'to the ends of theactuating shaft 20 and having pivoted thereon the links 22 forcooperating with the hanger rods 23 extend= Fixed to the actuating shaftis thedoor trip mechanism 24 .having' an extension 25 which is adaptedto cooperate with the flange 18 on,

the shuttle; After the bucket has been drawn outwardly along the boom bythe'cable 10 to the desired position, an inward pull on the cable causesthe shuttle to shift inwardly untilthe flan ge 18 strikes the extension.25, thereby causing dumping of the bucket.

i This dumping may be produced by either a direct reversal of the motionof the. bucket operating cable or the parts may be so arranged as tocause dumping by the stopping of the motion of the cable and allowingtheinertia of the bucket to trip the door.

In order to'restore the dumping mechanism to position for receiving thenextbatch from the mixing drum, a pair of extensions 26'and27 are formedon the tripping device 24 and are provided with rollers at the .ends

thereof. Fixed tothe boom adjacent the inward end are the cam members 30and 31 for cooperating with the rollers 28 and 29."

Assumingthe parts being in dumpedposition as shown by the dotted linesin Fig. 1,

roller 28 first engages ream 30 during the inward motion of thecarriage, causing the tripping mechanism to rotate the actuating shaft20 until the carriage has advanced sufficiently far to enable roller 29to engage 'cam 31. Continued movement of the carriage after roller 29has engaged 31 causes the door operatmg members to assume a p0 sition asshown by the full lines in Fig. 3,

the bell cranks 21 and links 22 passing the dead center position withrespect to the actuating shaft 20 and thereby producing a lookingaction. A means for adjusting the final position of thetrip mechanismisalforded by the'bolt 32 which may be adjusted with rela tion'to a stopmember 33 fixed to the carriage. In Fig. 2, the shuttle is shown ashaving anextension 34 on the upper portion thereof, constituting a guardor cable guide. Also in Fig- 3the carriage is shown as provided with theusual bumper device 35 for reduc-' ing the shock when the bucket reachesthe innermost position along-the boom.

1 The operation of the invention will be apparent from the foregoingdescription and v rection. Upon reaching the desired point along theboom at which the aggregates are to be dumped, themotion of the cable isreversed and an inward pull causes the shuttle to shift in a rearwarddirection until flange 18 engages the extension 25 on the trip member 24which rotates the actuating shaft 20 until the dead center relation ofthe bucket actuating members is destroyed and the bucket door fallsopen, thereby dumping the aggregates. A further inward pull on the cableshifts the shuttle still further rear-' wardly until the-flange 17engages the ex tension 5 on'thecarriage, whereupon motion is nowtransmitted to draw the carriage inwardly along the boom.

As the carriage approaches the inward end of the boom,roller'28'enga'ges cam 30 producing a partial clo'singof the bucketdoor.

Further inward motion of the carriage causes roller 29 to engage cam 31whichproduces a final closing and locking of. the door. Cams 30 and 31"are inspaced relation to permit roller 29 to be rotatedintopositionforengagement with" cam 31; When the bucket reaches the position forreceiving the i 1- 16, thereby securing the bucket against anyne'xt'batchaof a greg tes-gassing its inward travel, the latchmember-13'iis caused to "en; gage -st0pf12= under theactioniof thespring movement during receiving ofthe aggregates from the mlxlng drum.
